3,137,320 LOOM Agnes L. Parton, Owenoke, Westport, Conn. Filed Oct. 10, 1962, Ser. No. 229,615 1 Claim. (Cl. 139-33) The present invention relates to an improved loom and more particularly to an improved hand loom for weaving cloth.

Looms have been known for many years and comprise a plurality of warp threads which pass through the eyes of heddles and are controlled thereby. Depending upon the pattern to be formed a predetermined number of heddles, together with the warp threads that they control, are either lowered or raised to form a shed. A weft thread is then'passed through the shed substantially at right angles to the warp threads. The shed is then reversed, i.e. the previously raised warps are lowered and the previously lowered warps'are raised.

Mechanisms presently in use'for controlling the raising and lowering of the heddles are usually complicated. With such mechanisms, it has been difiicult to change a pattern because of the complex heddle controlling mechanism. In addition, duplication of such looms as toys has been difiicult because of the complicated heddle controlling mechanism and other complex structures.

The present invention eliminates these drawbacks and has for one of its objects the provision of an improved loom in which the heddles have been eliminated.

Another object of the present invention is the provision of an improved hand loom which does not require complicated pattern changing mechanisms.

Another object of the present invention is the provision of an improved hand loom which permits the pattern to be easily changed.

Another object of the present invention is the provision of an improved loom which can be easily duplicated as a toy.

Another object of the present invention is the provision of an improved hand loom which is simple to operate and inexpensive to maintain.

Other and further objects of the invention will be obvious upon an understanding of the illustrative embodiment about -to be described, or will be indicated in the appended claim, and various advantages not referred to herein will occur to one skilled in the art upon employment of the invention in practice.

A preferred embodiment of the invention has been chosen for purposes of illustration and description and is shown in the accompanying drawings, forming a part of the specification, wherein:

FIG. 1 is a schematic perspective view of a loom made in accordance with the present invention;

FIG. 2 is a sectional view taken along line 22 of FIG. 1;

FIG. 3 is a sectional view taken along line 3-3 of FIG. 2; and

FIG. 4 is a diagrammatic perspective view of the loom showing the shed reversed.

Referring more particularly to FIGS. 1 to 3, the loom 1 of the present invention comprises a frame 2 on which is mounted a warp roll 3 on which the warp threads 4a and 4b are wound. The warp roll 3 is supported on the frame 2 by a shaft 5 which is provided with a pair of wheels 6. The wheels 6 have a plurality of openings 7 therein adapted to receive a pin 8 which acts as a stop to prevent the warp roll 3 from being rotated, when desired.

A take up reel 10 is mounted at the other end of the frame 2 and is adapted to take up the fabric which is formed on the loom. The take up reel 10 is also jou 3,137,320 Patented June 16, 1964 nalled in the frame by a shaft 11 which has wheels 12 fixedly mounted thereon with slots 13 being adapted to receive a pin 14 to prevent the wheel from rotating.

Warp threads 4a and 4b pass from the boom 3 between separators 15. The warp threads 4a and 4b pass through eyelets 16a and 16b, respectively. The eyelets 16a and 16b have control strings 30a and 30b, respectively, depending therefrom with loops 17a and 17b, respectively, at their extremity.

The loops 17a and 17b of the control strings 16a and 16b are adapted to be inserted on pattern sticks 18a and 18b, respectively, in a predetermined manner depending on the desired pattern. In the embodiment shown in the drawings four pattern sticks are shown, i.e. pattern sticks 18a and 18b, and a selected number of con trol strings 30a aremounted on the pattern stick 18a and the remaining control strings 30b are mounted on pattern sticks 18b. Thus eyelets 16a (with warps 4a) arecontrolled by pattern stick 18a and eyelets 16b (with warps 4b) are controlled by pattern sticks 1817. This will permit a fabric having a particular pattern to be formed by the loom. Itwill be understood that if a different pattern is desired it is merely necessary to rearrange the mounting of loops 17a and 17b on the pattern lower rod 21 and upwardly over an upper roll 22. Pattern strings 20a and 20b have second loops 23a and 23b adapted to permit the strings to be connected to the roll 22 by any desired means, such as pegs 24a and 24b, respectively. In the embodiment shown in the drawing in FIGS. 1 to 3 it will be noted that the three pattern sticks 18b are fixed to the upper roll 22 by having the loops 23b of the pattern strings 20b hooked over the pegs 24a while the fourth pattern stick 18a is not attached to the upper roll 22 since'the pattern string 20a does not have its loop 23d hooked onto peg 24a. Hence pattern stick 18a, and warp threads 4a controlled by it will not move when the upper roll 22 is rotated. For convenience, the

loop 23a of pattern string 20a may be hooked over idler stick 35.

When it is desired to form the shed, as shown in FIGS. 1 to 3, the upper roll 22 is rotated in a counterclockwise direction as shown in FIG. 3 so that the pattern sticks 18b which are operatively connected to pegs 24b will be moved down thereby pulling the eyelets 16b connected thereto downwardly. The warps 4b which extend through these eyelets 16b will be moved down to form the lower part of the shed.

It will be noted that the eyelets 16a which are not 0peratively connected to the upper roll 22 are not moved downwardly since the rotation of the roll 22 will have no effect on them. To form the upper part of the shed, the eyelets 1611 must be moved upwardly. A magnet, such as the permanent magnet 25 depending from upper roll 22 by means of strings 27, is first lowered so as to attract eyelets 16a by its magnetic field and is then raised to pull the eyelets 16a and the warps 4a controlled thereby upwardly and form the upper part of the shed as shown in FIG. 3. With the shed in this position a weft thread 26 may be inserted in the shed as shown in FIG. 1.

The shed is then reversed as shown in FIG. 4. This may be done by removing the loops 23b from the pegs 24b of the three pattern strings 20b and mount them on idler stick 35 so that they are free from and do not move to peg 24a so that the string 20a moves with the upper roll 22. Thus the position of the eyelets 16a and 16b are reversed and the eyelets 16a will be moved down by E a rotation of the upper roll 22 while the eyelets 16b remain stationary.

The upper roll 22 is again rotated counterclockwise so that the eyelets 16a, which are under the control of the upper roll 22 are lowered whereas the eyelets 16b which are not under the control of the upper roll 22 are not lowered. The permanent magnet 25 then pulls eyelet 16b upwardly to pull warps 4b upwardly and thus reverse the shed as shown in FIG. 4,

The whole process is then repeated to form the fabric 15. The pattern formed with the loom having the pattern sticks arranged as shown in the drawings is a simple 3 and 1 pattern, i.e. three warps alternate with one warp for each Weft. However, other patterns may be produced by simply changing the portion of loops 23 on pegs 24 or changing the arrangement of the pattern sticks 19 with respect to the loops 17.-

Thus it will be seen that the present invention eliminates the complex pattern producing mechanisms which have heretofore been used on looms. Furthermore since the mechanism for controlling the raising and holding of the heddles has been eliminated, looms are simpler to operate and may easily be duplicated in the form of a toy, if desired. 7 1 I As various changes may be made in the form, construction and arrangement of the parts herein without departing from the spirit and scope ofthe invention and without sacrificing any of its advantages, it is to be understood that all matter herein is to be interpreted as illustrative and not in a limiting sense.
